Nested loops and asterisk patterns

[otorp2]

Change text asterisk to rect - simple is beautiful

int i, j;
void setup() {
  size(190,200);
  background(200);
  fill(0);

  for(i= 0; i <= 9; i++) {
    for(j=0; j <= i+1; j++) {
    //text("*", i*10, j*10);
      noFill();
      rect(0,0,i*10,j*10);
      }
   }
}
